CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 336,322, dated February16, 1886.

' Application filed August 12, 1895. Serial No. 174,198. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES MYRoN INGER- soLL, of Summit Hill, in thecounty of Carbon and State of Pennsylvania, have invented a new anduseful Iniprovementin Car-Couplings, of which the following is a full,clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part ofthis specification,

in which similar letters of reference indicate corresponding parts inall the figures.

Figure 1 is aside elevation of one of my improved car-couplings shownuncoupled. Fig. 2 is a plan view of one part of the same, part of thelink being broken away. Fig. 3 is a front elevation of a part of thesame. Fig. 4 is a sectional side elevation of a part of the same. Fi 5is a plan View of the coupling bar or link.

The object of this invention is to provide car-couplings constructed insuch a manner that they will couple automatically when the ears are runtogether, and can be readily uncoupled,and which shall be simple inconstruction, strong, durable, and not liable to get out of order.

The invention consists in the construction and combination of variousparts of the carcoupling, as will be hereinafter fully described andthen claimed.

A represents the draw-heads, the mouths of which are made hoppershaped,as shown in Figs. 3 and 4, and indicated in dotted lines in Fig. 1. Theshanks of the draw-heads A are slotted longitudinally and horizontally,to allow the ends of the coupling-bar B to have a free lateral movement,and the height of the said slots are made enough greater than thethickness of the coupling-bar B to allow the ends of the saidcoupling-bar B to have the necessary vertical play.

0 are the coupling-pins, which pass down through holes in the shanks ofthe draw-heads -A and through slots in the end parts of the coupling-barB. The upper ends of the coupling-pins-O are pivoted to latches D at alittle distance from their rear ends, so that the said pins will beraised and lowered by the up and down movements of the said latches. Thelatches D are pivoted at their rear ends to lugs formed upon or securedto the upper sides of the shanks of the draw-heads A, and

their forward ends extend nearly to the forward ends of the saiddraw-heads.

Upon the lower sides of the forward ends of the latches D are formeddownward pro jections D, the inner edges of which are concaved, andtheir outer edges are convexed, giving to the said projections a hookform, as shown in Figs. 1 and 4.

The projections D of the latches D work in slots in the upper and lowerparts of the draw-heads A, and the said latches D are made to move upand down in vertical planes by keepers E, attached to the upper sides ofthe said draw-heads, and are held down by V-shapcd springs F, which aresecured at or near their angles to the rear parts of the said latches D,with their lower arms resting upon the upper sides of the said latches,and with the ends of their upper arms passing through the upper parts ofthe keepers E, and bearing against the bends of the said keepers. \Viththis construction, when two cars are run together, the entering end ofthe coupling-bar B strikes against the convexed forward edge of theprojection D, and raises it and the latch D, and pin Opasses in beneaththe lower ends of the said projection and pin until they drop throughthe slot in the said couplingbar B. The coupling-barB is made withtapered ends, as shown in Figs 1 and 4, and the said ends are made solidfor such a distance that the ends of the projections D will rest uponthe said ends until the said ends have passed beneath the lower ends ofthe coupling-pins G, which then rest upon the said solid ends until theyslide off into the slots of the said coupling-bars, and the cars arecoupled,the draft-strain coming wholly upon the couplingpins 0.

The center of the coupling-bar B is made solid, to give it the necessarystrength, and the middle part of the said bar is widened and has theends of the said widened part beveled, to correspond with the flare ofthe mouths of the d1aw-heads, so that the distance to which thecoupling-bar enters the draw-heads will be limited by thesaid widenedpart of the coupling-bar coming in contact with the inner surface of thedraw-heads.

Upon the pivoted rear end of each latch D can be formed, or to it can berigidly attached, an arm, G, to serve as a foot-lever for raising thelatch D to uncouple the cars, or an arm, H, to receive a chain connectedwith a lever pivoted to the front of the car-body; or to the forward endof the latch D can be pivoted the forward end of a lever, I, the middlepart of which is pivoted to a standard, J, attached to the shank of thedraw-head; or to the forward end of the latch D can be attached aneyebolt. K, to receiveachain connected with the top of the car-body, orto serve as a handle for raising the said latch and'uncoupling the cars.

A hole, L, is formed through the forward part of each draw-head A,toreceive an ordinary coupling-pin, M, when it is necessary to" couple acar provided with my improved coupling with a car provided withtheordinary pin-and-link coupling. The coupling-pin M is connected wilh thedraw-head A byashort chain, N, so that it cannot be lost, and when notrequired for use is inserted in keepers 0, attached to the side of thedraw-head A. c When it is desired that cars may be run together withoutcoupling, the latch D and pin 0 are secured in a raised position by apin, 1?, inserted in a hole formed in the keeper E. The pin 1? isconnected with the draw-head A by a short chain, Q, to keep it frombeing lost, and when not requ red for use is inserted in keepers R,attached to the side of the drawhead A.

Having thus fully described my inventioml claim as new and desire tosecure by Letters Patent- 7 1. In a car-coupling, the combination, withthe draw-head A, the coupling-pin G, and the coupling-bar B, of thelatch D, carrying the said coupling-pin, and provided with a hookshapedownward projection, D, the keeper E, to guide the said latch, and thespring F, to hold the latch down to its place, substantially as hereinshown and described, whereby the cars will be coupled automatically whenrun together, as set forth. r

2. In a car-coupling, thecombination, with the,draw-head A,'the latch D,carrying the coupling-pin O, the guide-keeper E, and the spring F, ofthe arm G, substantially as herein shown and'described, whereby the saidlatch and coupling-pin can be readily raised to uncouple the cars, asset forth.

3. In a car-coupling, the coupling-bar B, made, substantially as hereinshown and described, with solid tapered ends, with a solid center, andwith its middle partwidened and beveled at the ends of the said widenedmid- 55 die part, substantially as herein shown ands;
